TS Optics 1.25" Helical Focuser and variable Extension

With the TSFOCH1, we offer a highly versatile adapter. Adjustment and focusing are simply done by turning the receptacle. The rubber coating guarantees a firm grip.

One part - three uses!

♦ variable 1.25 extension with fine focusing: The TSFOCH1 can be used simply as variable 1.25 extension. The path can be adjusted between 45 mm and 61 mm. The sensitive rotation allows for very precise focusing - ideal for all telescopes with main mirror focusing, like Schmidt-Cassegrains.

♦ variable T2 extension with fine focusing: Simply put the 1.25" connection adapter into the receptacle (with compression ring) and the 1.25" extension turns into a T2 extension with female M42x0.75 thread at the telescope side and the corresponding male T2-thread at the camera side.

♦ 1.25" and T2 helical focuser for amateur telescope making: Also a possible implementation for all amateur astronomers who want to build a small telescope by themselves. The connection to the tube is simply made by the T2-thread or the 1.25" receptacle.
